- VALVE-REMODELING DEVICE.

SPECIFICATION forming part of Letters Patent No. 651,548, dated June 12,1900.

Application filed October 2, 1899.

T all whom, it may concern:

Be it known that I, CHARLES E. HUXLEY, of Aurora, in the county of Kaneand State of Illinois, have invented certain new and useful Improvementsin Valve-Remodeling Devices; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of refer- 1o ence marked`thereon, which form a part of this specification.

This invention relates to an improved device in the nature of a handimplement for remodeling valve-seats, the purpose of the i5 inventionbeing to provide an implement which maybe adjustably secured to avalvecasing in position for a cutting-tool, which forms a part of theimplement, to operate upon the valve-seat. The implement isisimi- 2o larin character to that shown in .my prior United States Letters Patent,No. 614,226, dated November l5, 1898.

The invention herein shown refers more particularly to an improved meansfor detachably securing the implement to the valvecasing. v

Other features of improvements of the character set forth are, however,disclosed, as will hereinafter more fully appear.

The invention consists in the matters hereinafter described, and moreparticularly pointed out in the appended claims. Y

Fig. 7 is a view from beneathof the chuck-actuating ring. Fig. 8 is a detail section thereof, takenon line S 8 of Fig. 7. Fig. 9 is atop plan View of one of thechuck-jaws. Fig. 10 is a side eleva,- tion of the spindle which carriesthe cutting- 5o tool.

In said drawings,

A A indicate a valve- Serial No. 732,268. (No model.)

casing, such as that of an ordinary globevalve, said casing beingprovided with a valve-seat c and with a screw-threaded opening A', whichwhen the valve is in use rc- 55 ceives the head which carries theValvespindle.

B desiguales a plate which is provided with means by which it may bedetachably connected with the valve-casing and serves to 6o support orsustain the other parts of the implement in position for action upon thevalve-seat. l

O designates a supporting-plate which is secured to the attaching-plateB by means of an annular outwardly-projecting flange B', concentric withand on the outer side of said attaching-plate, said liange beingprovided with exterior screw-threads for engaging with the interiorscrew-threads provided in a cy- 7o lindric recess on the inner side ofsaid supporting-plate. A screw-threaded ring O' surrounds thescrew-threaded flange B' of the attachingplate below thesupporting-plate' C and is adapted for contact with said plate, so as toform in effect a jam or locking nut, which acts to hold the plate Ofirmly in place upon the attaching-plate. Said ring is provided'onopposite sides with notches c,adapt ed to ybe engaged hy a Spanner orlike tool. 8o Said plate O is provided with a centrally-arrangedtransverse slot or opening O2, and on opposite sides of said slot areformed two parallel guide-flanges O3 O3, provided on their -inner facesat their bases with grooves c.

Between said flanges are located two sliding blocks D,'provided at theirupper and lower edges with outwardly-extending flanges d d', of whichthe outer flange d extends over the top surfaces of the guide-flanges C3and 9o the inner flange d engages the grooves c therein. Each of saidsliding blocks is provided at one end with a laterally inwardlyextending arm or cross-piece D', which extends nearly to the inner faceof the opposite sliding block. Between said sliding blocks is located aswivel block or head E,which has pivotal connection with said slidingblocks in the manner shown in said prior patent, and to l said head isattached a screw-threaded sleeve roo E', which extends outwardlytherefrom. Through said head and sleeve passes a shaft or spindle F,which is adapted for actuation by means of a crank-arm F', attached tothe outer end thereof. Said spindle is provided at its inner end withmeans for attaching a cutting-tool thereto-such, for instance, as thetap G (shown in the drawings)-and is screw-threaded at its lower end toreceive a securing-nut J. The purpose of the sliding blocks D D,together with the swivel-block E and clamping device for holding saidparts in position, is to adjustably support the toolcarrying spindle Fin proper position with respect to the valve-seat to be operated upon.The details of construction by which these parts are adjusted and heldin their adjusted positions are substantially like those shown in mysaid prior patent, said swivel-block E being pivoted to the slidingblocks D, so as to enable the tool-spindle to be swung in an inclined oroblique position. The slidingblocks are clamped in rigid relation withrespect to the guide-flanges C3 by nieans of set-screws I-I, which areinserted through said guides and act against the outer face of thesliding blocks. The sliding blocks on the guideflanges C3 enable theswivelblock to be bodily moved transversely, as may be required, toincline the spindle to bring the cutting-tool accurately in place withrespect to thc valve-seat. The arms D of the sliding blocks are providedwith set-screws H', which are adapted to bear against the head E, whichlatter is curved at its inner end to afford a bearing-surface for saidscrews concentric with the pivotal axis of the head.

In order to adjust a tool to an angle with respecttothe valve-casing, asrequired where the valve-seat is not parallel with the opening of thevalve-casing, it will be necessary to turn the supporting-plate C on theflange B so as to bring the guide-anges C3 thereof parallel with theplane of the inclination of the tool-spindle, and this adjustment of thesupportingplate is readily effected by loosening the locking-ring C andthen turning the supporting-plate to the desired position, after whichsaid ring will be tightened against the supporting-plate to preventfurther turning of said plate and hold the latter fixedly in place.

As a lneans for feeding or advancing the spindle and the tool as thework progresses devices are provided as follows: The sleeve E isprovided with an external screw-thread, which is engaged by aninteriorly screwthreaded sleeve or nut I, provided at its outer end witha radial tiange l', constituting a hand-wheel by which the sleeve may beturned. Above the flange l is a disk l2, which is connected with thesaid flange by two arms t' fi, and between the said disk l2 and said.flange is located a collar F2, which fits between and engages saidflange and disk. Said collar is provided with a set-screw f', whichengages at its inner end the spindle F and by means of which said collarmay be adjustably secured to the spindle. Said collar constitutes ameans of holding the sleeve l from end wise movement with relation tothe spindle, so that when the sleeve is turned its screw-threadedconnection with the sleeve E will act to advance the spindle and tooltoits work. The spindle is cut away on the side thereof engaged by theset-screw f', thereby forming a flat surface f2, and said surface isinclined upwardly, as shown in Fig. 5, the dotted line in said figureindicating the original contour of the spindle. The purpose of incliningthe surface f2 is to prevent the spin dle from moving upwardly throughthe collar F2 in the upward thrust given thereto when the sleeve I isturned to feed the tool forward against the work. It will be understoodthat the collar F2 will be locked to the shaft only when a cutting-tool,such as a reainer or the like, is being used, and when a tap is beingused the feeding device described will not be required and the spindlewill be allowed to slide freely through the sleeve E', so as to followthe tap in its advance movement. The spindle F is provided with agraduated scale,

as shown, to enable the operator to readily.

determine the extent. of inward movement when a tap is being used, atwhich time the spindle passes freely through the sleeve E. An adjustablecollar l3 on the sleeve t forms a stop for the sleeve l, by which theadvance movement of the tool may be accurately limited when the same isbeing fed forward by the turning of said sleeve I.

Referring now to the means for detachably conngcting the attaching-plateto the valvecasing A, these parts are made as follows: Theattachingplate B is provided on its inner side with a plurality ofradial grooves B2, which are herein shown as formed in thickened partsor ribs in said plaie. lVithin said grooves B2 are inserted chuclejawsB2, which are provided with means for moving the same radially inwardand outward upon the plate B. Said grooves are herein shown as madeT-shaped in cross-section, and the jaws are provided withoppositely-directed longitudinal flanges which interfit with said grooveand prevent the jaws from falling out of place. Said jaws are providedwith a plurality of radially-separated offset surfaces b, there beingthree, as herein shown, and the corresponding surfaces of each of saidjaws are formed at an equal distance from the inner ends of the jaws, sothat when said jaws are in place within the grooves B2 such corresponding surfaces will be included in a circular line concentric withthe center of the plate. Said offset jaws are provided withscrewthreads, and the jaws are adapted to be moved radially inward andoutward, so that the serewthreads of one of the sur faces of each of thejaws will engage the interior screw-threads in the aperture A' of thevalve-casing. Vith this arrangement the screwthreaded radially arrangedjaws form, in effect, a stud secured to the attaching-plate and whichhas screw-threaded en- IOO ICS

gagement with the aperture A of the casing. The screw-threaded surfacesadjacent to the outer ends of the jaws will be employed in connectionwith valve-casings having relatively-large openings A', while thoseadjacent to theinner ends of the jaws will be employed with smallervalve-casings. Means are provided for simultaneously moving said jawsradially outward and inward to enable the implement to be attached tovalves having different-sized openings, and means are also provided forlocking said jaws in any adjusted position. The means herein shown forthis purpose are made as follows: The upper edges of said jaws withinthe slots are provided with a plurality of teeth or notches b', whichwhen the jaws are in proper position in the plate B are arranged on aspiral line passing from the inner to the outer ends of the jaws. B4designates a chuck-actuating ring` which is located in an annular recessB5, formed upon the outer side and adjacent to the periphery of saidattaching-plate. Said actuating-ring is provided on its inner face witha spiral screw-thread b2, which when the ring is in place upon the plateB engages certain of the teeth or notches b in the upper face of thejaws B3. The part of said plate occupied by said annular recess B5beingin a plane inside of the outer parts of the grooves,

openings are formed in said recess opposite to said radial groovesthrough which said screw-thread of the actuating-ring and teeth of thejaws project and by means of which connection is aitorded between thesame. Said actuating-ringis provided inside of said screw-threads withan annular bearing-surface b4, which engages the upper surfaces of the,chuck-jaws B3 and by means of which said jaws are clamped orheld inplace. Said actuating-ring is provided in its periphery with a pluralityof notches b5,\vhich are adapted to be engaged by a suitable implement,such as the Spanner .l shown, by which the said ring may be rotatedtom'ove the jaws inwardly or outwardly, as desired. A lockingring B6surrounds the outwardly-projecting annular flange B of theattaching-plate above or outside of said actuating-ring and serves whenscrewed down upon the actuating-ring to force the same against thechuck-jaws, and thereby rigidly lock and hold the same from movement,the bearing-surface h4 and also the screw-threaded part of saidactuating-ring coming in contact with the teeth of the chuck-jaws whenthe ring is forced toward the said jaws by the action of thelocking-ring. Said locking-'ringis provided with notches h6, by which itmaybe engaged by a Spanner to move the same into and out of its lockingposition. As shown in Fig. 5, the locking-ring B6 is moved awayfrom theactuating-ring to enable the latter to be turned to adjust thechuck-jaws B3. As a further and separate improvement said chuck-jaws areso arranged that they may be made to engage either an interior orexterior surface of the valve-casing, so that the implement may be usedas well upon a valve-casingin which the head is secured thereto throughthe medium of external screw-threads as in the instance illustrated.This is accomplished by removing the jaws from the grooves B2, reversingand inserting them into said grooveswith the screw-threaded surfaces l)thereof facing inwardly. In order that the screw-thread of theactuating-ring may accurately engage the teeth b of the jaws and movesaid jaws inwardly and outwardly when the latter 0ccupy either ot' thepositions mentioned, the opposite sides of each of the said teeth areoppositely curved, as shown in Fig. 9, the curvature thereofcorresponding with the curvature of the portion of the screw-thread ofthe actuating-ring which engages said teeth. this means space isprovided between said teeth for the short curved portion of thescrew-thread which stands opposite the same when the engaging faces ofthe jaws are facing either inwardly or outwardly. The construction lastdescribed is of much importance,asit greatly increasesthe capaciiyof theimplement for work by enabling it to be used upon valve-casings in whichthe head is secured thereto either' by interior or exteriorscrew-threads.

The construct-ion described, in which the attachingplate is providedwith a plurality of radially-movable chuck-jaws, with `a screwthreadedactuating-ring adapted to bear against the jaws and a locking-ring whichforces the actuating-ring into clamping engagement with the jaws, is ofgreatimportance, as it enables the implement to be readily adjusted tovalve-casings of various sizes and at the same time affords anexceedingly-rigid connection between the same when the jaws have beenlocked in their adjusted position.

In the operation of the implement when the same is to be employed inconnection with a valve-seat which is arranged in a plane parallel withthe upper surface of the casin g A the chuck-jaws B3 will bemovedinwardly against the lool-spindle F for the purpose of centeringsaid spindle, so that the tool connected thereby will accurately engagethe valve-seat,after which the jaws will be moved outwardly, with theirscrew-threaded faces b in contact with the interior screw-threaded valve-casinoz Said jaws are shown in Figs. l, 3, and 5 in position to centerthe spindle F and are shown in dotted lines in Figs. l and 3 in theouter Vor clamping position. When said jaws are moved outwardly intoengagement with the screw-threads of the casing, the inner ends thereofwill be moved a sufficient distance from each other to provide room forthe required movement of the tool-spindle when the latter is inclined toadapt the cutting-tool to an inclined valve-seat.
